ABSTRACT:
A multi-mode modulator includes a first data path to process in-phase signals in a quadrature modulation mode, a second data path to process quadrature signals during the quadrature modulation mode, and a first multiplexer to selectively switch polar amplitude data onto one of the first and second data paths in response to a selection signal.
